Xx July 1999 <br />AGE -NC Project No. 99-0557 <br />Page 4 of 8 <br />Soil samples collected from hydraulic lift locations P-6 and P-12 were additionally analyzed for: <br />PCBs by EPA Method 8080. <br />4.3. GROUND WATER SAMPLE COLLECTION AND ANALYSIS <br />Ground water samples were collected from soil probe borings P-6, P-12, and P-17. Ground water <br />table was encountered at approximately 13 feet bsg. Ground water samples were collected from the <br />top of the ground water table in probe borings P-6 and P-12 at a sampling interval of 13 to 18 feet <br />bsg. A ground water sample was collected from boring P-12 at a sampling interval of 11 to 16 feet <br />bsg. Ground water sample collection procedures are presented in Appendix A. <br />The ground water samples were submitted to MAI and analyzed for: <br />BTEX by EPA Method 8020; and <br />TPH-g, TPH-d, and TPH-mo by EPA Method 8015 Modified/5030. <br />The ground water sample collected from the former gasoline UST location (P-17) was additionally <br />analyzed for: <br />Fuel oxygenating compound - MTBE by EPA Method 8260. <br />5.0. FINDINGS <br />Discussion of shallow subsurface soil profile observed at the site, as well as soil and ground water <br />analytical results are presented below. <br />5.1. SHALLOW SUBSURFACE SOIL PROFILE <br />Shallow subsurface soil at the site appears to consist primarily of coarse -grain deposits of sand with <br />silt from ground surface to approximately 15.5 feet bsg. Fine-grained deposits consisting of silty clay <br />with sand and silty clay/clayey silt were encountered at approximately 25 to 30 feet bsg. Logs of the <br />soil probe borings are presented in Appendix B. <br />Petroleum hydrocarbon discoloration, odor, and/or OVM readings above background levels were <br />only observed for soil samples collected from soil probe boring P-6. The highest OVM reading of <br />5.6 parts per million (ppm) was measured for a soil sample collected from soil boring P-6 at <br />Advanced GeoEnvironmental, Inc. <br />
